Specification of Letters Patent.

Patented Apr. *7, 1914:.

Application filed October 28, 1913. Serial No. 797,811.

To all whom it may concern:

Be it known that I, CARL RAoH, a sub ject of the King of Prussia, andresiding at Stapleton, in the county of Richmond and State of New York,have invented a certain new and useful Improvement in R0- tary Presses,of which the following is a specification.

The present invention relates to rotary presses and particularly tobrewers presses of the type shown in my Patent 1,018,267, dated February20, 1912.

The object of my invention is to improve the rotary pressure disks byrendering them more efficient, lighter, easier to clean and repair, andat the same time more durable.

In the accompanying drawing, Figure 1 is a side elevation of a pressuredisk with portions removed or broken away Fig. 2 is a cross sectionthereof on the line 22, Fig. 1; Fig. 3 is a perspectiveof one of thesegmental perforated web plates; and Fig. 4. is a perspective of one ofthe segmental screens.

In my patent above mentioned, I have shown a pressure disk withremovable segmental facing screens. The body of the disk however isshown in common form with radial arms extending from hub to rim andunited by channeled webs, cast,

integral therewith. When it is desired to clean the press ithasconsequently been necessary, after the screen segments are removed,to wash out the interior of the press, including the webs, by means of ahose introduced through the door of the press. This is not only awkwardbut inefiicient, since it is possible in this manner to reach but oneside of the webs and practically impossible to clean their outer facesand the interior walls of the press. Furthermore, the webs being of castiron and being subject to attack by the acids of the beer wort, it hasbeen necessary to make them fairly heavy, so that they may not berapidly eaten away and the disk rendered useless. Furthermore, andpartially for the same reason, it has been impracticable to make thechannels as numerous as might be desired to let the liquid escape freelyand in view of'their relative. small capacity and liability to becomeclogged, it has been necessary to clean away frequently or to dischargethe material imperfectly dried.

These defects have been remedied by the present improvement whichconsists, briefly, 1n making the webs independent of the body of thedisk, forming them of perforated plate metal, preferably of a substancewhich is not attacked by the acids of the beer worts, and supportingthem in seats on the face of the disk so that they may be easily removedwith thesegmental facing screens.

A suitable construction in which my invention is embodied,,isillustrated in the accompanying drawing. As here shown the hub 10 iscast integral with the radial ribs 11 which connect the hub to the rim12. A seat 13 is formed by offsetting the ribs, hub and rimsurroundingthe aperture or open field 14C formed by omitting the usualweb bet-ween these parts. A perforated rigid plate 15 shaped to thisaperture and of a thickness substantially corresponding to the depthofthe seat, rests in the latter with its outer face substantially flushwith the outer face of the disk. After the adjust ment of the slide bars16 the screen 17 is slid in above the plate 15 and serves to retain itin its seat. The retaining bar 18 prevents the screen 17 from fallingout.

A gear supporting ledge or ring 28 is cast integral with ribs 11 and isunited with the rim 12 by fins 19 extending between the two. As hereshown these fins serve the double function of strengthening the ring 23and of forming an auxiliary support for the perforated plate 15. Inorder not to obstruct the perforations of the latter the supporting faceof the fin is beveled to an edge 20 which is interrupted at intervals bycross channels 21 to facilitate the escape of the .liquid. .Obviously ifthe plate is strong enough to stand the strains of the press withoutthis auxiliary support, the fins may be carried from the rim to the gearsupporting ledge 23 entirely out of contact with the plate. The gearring 22 is slipped over the ledge 23 and bolted in positionsubstantially as shown.

The use of a perforated plate 15 of the character described, is anadvantage from the standpoint of efiicient drainage, since it ispossible to use a plate having a much larger number of drainage holesthan it is practically possible to form in the old style web. Thisadditional drainage results in more complete and rapid drying of the wetgrains as they pass through the press. Again, since the liquid finds aready outlet thereis less expense in power required to operate thepress. There is no clogging. An obvious advantage also lies in thefacilitation of repairs, and cleansing, since the plate 15 may be takenout through the door of the press in like manner as the segmental screendescribed in my patent above mentioned. By reason of the fact that theplate is of less weight than the old web, there is less frictional wearon the disk bearings and consequently longer life for the press.Furthermore, as above mentioned, it is possible to make the plate out ofmetal different from that of the body of the disk and of such naturethat it is not affected by the acids of the liquid coming from the mashgrains. For this purpose bronze may be utilized, thus materiallyincreasing the life of the disk.

I claim as my invention:

1. A pressure disk for a rotary press of the character described,comprising hub, rim and interconnecting radial ribs dividing the diskinto a plurality of segments, a seating around the inner periphery ofeach segment, a removable perforated plate segment resting in theseating in each segment, together with an independent superposed screenoverlying the plate in each segment, substantially as described.

2. A pressure disk for a rotary press of the character described,comprising hub, rim and interconnecting radial ribs dividing the diskinto a plurality of segments, a seating around the inner periphery ofeach segment, a removable perforated plate seg ment resting in theseating in each segment, and having its outer face substantially flushwith the face of the disk, together with an independent superposedscreen overlying the plate in each segment, substantially as described.

3. A pressure disk for a rotary press of the character described,comprising hub, rim and interconnecting radial ribs dividing the diskinto a plurality of segments, a seating around the inner periphery ofeach segment, a removable perforated plate segment resting in theseating in each segment, together with an independent superposed screenoverlying the plate in each segment, and forming the means for retainingsaid perforated plate in its seating, and readily detachable means forsecuring said screen in position, substantially as described.
